Only the io.serializations are actually exposed. Which includes "KVSerailization". Generally the mapper's output value class are not configurable whereas we directly set them if the user tries to use it. Since KV is private then we should expose only the interface Cell then as it is public. But again am not sure if Mappers work with interfaces alone and do they need concrete implementations as the type? > Deprecate KV Usage in MR to move to Cells in 3.0 > ------------------------------------------------ > > Key: HBASE-18649 > URL: https://issues.apache.org/jira/browse/HBASE-18649 > Project: HBase > Issue Type: Improvement > Components: mapreduce > Affects Versions: 2.0.0-alpha-2 > Reporter: ramkrishna.s.vasudevan > Assignee: ramkrishna.s.vasudevan > Fix For: 2.0.0, 3.0.0, 2.1.0 > > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
